Senate Must Not Be Much Fun

Sen. Ken Salazar (D-CO) will be President-Elect Obama's nominee for the Interior Department.

(To be clear, Interior is a very big deal for Western states like Colorado. I'm well aware of that. But I continue to be surprised how many relatively young senators -- Salazar is 53 and he was elected in 2004 -- are willing to give up their seats to serve in Obama's cabinet.)
